Vision
Monitoring water is becoming more and
more important. Resources, particularly
drinking water are extremely limited. In
areas requiring irrigation, especially in
very dry districts, man is already fighting
to make good use of the last drop.
Without doubt, the acoustic discharge
measurement has enhanced its prestige.
It is used as a fundamental information
for water management in the field of
hydrology, for the control of processes
in the field of hydro power as well as
for water supply, industry and waste
water applications.
The acoustic principle has become a
growth driver for flow meters. More
and more users have already begun to
appreciate the advantages of contact
free measurements. With a comprehen-
sive range of products and solutions we
can determine flow in various applica-
tions. Accuracy and reliability are given
top priority. HydroVision products owe
their quality to rigorous testing under
laboratory conditions and their con-
tinuous development. We are not
satisfied until our instruments meet the
required accuracy under real field
conditions.
HydroVision’s broad knowledge in the
area of acoustic flow measurement is
reflected in our product range for stan-
dard applications. It becomes even more
apparent when complex tasks have to
be solved.
HydroVision is committed in equal mea-
sure to consulting, delivery quality, service
and support.
Water is a valuable commodity, with
which we feel connected in a special
way. HydroVision is passionate about its
products and can look back on many
years of experience. HydroVision starts
where others stop. We are continually
developing our product range to stay
one step ahead. This enables us to
reliably solve all your measuring tasks.

In this product overview we describe the various
applications for our instruments. A vast amount
of applications can be solved using acoustic flow
measurement. HydroVision is at the forefront of
“State of the Art” and future development.
Our measurement instruments can be used everywhere
where there is flowing water. For example rivers,
channels or pipes – we measure everywhere.

When sound propagates through water, pressure
fluctuations can be detected. They travel through
the water, the channel or the pipe as sound waves.
With our instruments it is possible to record these
ultrasound waves.
Depending on the measurement technique applied,
we detect the Transit Time with and against the flow
direction. For other applications we use the Pulse
Doppler effect. Here our instruments record the change
of the wave length reflected by a particle in the flow.

Rivers
Numerous rivers intersect our landscape from small
brooks up to huge river networks. Some of them form
a natural border between two countries.
At all times man has preferred to live in river areas.
Clear water, the possibility to use the river for trans-
port, generating power from water and the scenic
beauty are amongst the reasons. However, our actions
have more and more influence on water quantity and
quality. In many regions taking water for irrigation
or as drinking water are the reasons. More than half
of all big rivers around the world have been polluted
during the course of time.
Observations of water levels have been used since
ancient times, systematic flow measurements go back
to the middle of the 19th century. This historical data
has been used as the basis for various applications, for
example for flood protection and flood
forecasting. They also form the foundation for the
design of hydro-engineering constructions. In recent
years the acoustic flow measurement has established
itself as the standard method for measurements on
many hydrological stations. With this almost contact
free technology data can be recorded continuously
and it provides 24/7 monitoring.

Products
The range of application for Fluvius TT runs from small waterways to huge river systems with high
suspended solids. By means of acoustic transmission a coded signal is sent through the water and
the transit time is calculated providing the speed of river flow. When an acoustic wave propagates
in water, part of the energy is damped by friction and suspended solids. This procedure is frequency-
related. The higher the frequency, the bigger the damping. For wider distances we use low
frequencies as they allow for a considerably better receiver signal.

Channels
Channels are artificially created waterways used for
shipping, transportation, irrigation, drainage and
for cooling water extraction of power plants.
A further important use is the transportation of water
used for the supply of drinking water. Here the focus
lies on detecting water loss at an early stage; some-
times it is difficult to detect small leakages.
Our instruments measure precisely and reliably in
order to prevent long term water losses.

Mounting Assembly
Standardized mounting devices for any kind of channel ge-
ometry like rectangular, trapezoid or natural river banks are
available. The flow optimized design protects the transducers
against moving objects suspending in the flow stream. It also
provides room for connections and protective conduits.
Transducers
TD-200/8
In its most basic form, the
system operates with a single
pair of transducers.
However, it relies upon a relatively
stable velocity profile, essentially
unaffected by changes in the rela-
tion between water level and flow.
The main flow has to be paral-
lel to the bank. The relationship
between measured velocity and
flow is established by hydrometric
calibration.
In rivers there is a high risk of
cross flow. Its intensity depends
mainly on the river’s geometry
and if there is an upstream bend
in the river.
Although the cross flow does not
influence the quantity of the
flow, it may affect the mea-sure-
ment, a second pair of trans-
ducers will be necessary.
By crosswise arrangement of four
transducers, effects of changing
flow direction can be eliminated.
An even more accurate flow mea-
surement can be obtained with
systems using several planes.
The measured result can be
further improved by using a multi
path system layering each of the
acoustic paths in parallel planes
one above the other. This negates
having an expensive hydrometric
calibration.
This type of system is suitable for
applications with large water level
fluctuations, reverse flow or a ver-
tical velocity distribution outside
the theoretical normal.

Hydro Power
Hydro power is an important source of energy which
contributes to supplying power to the earth’s popula-
tion. Today, hydro power plants deliver approximately
3,5 per cent of electric energy generated worldwide.
Their share in power generation from renewable re-
sources comes to 18 per cent. In the future this share
will continue to grow, as resources of fossil fuels are
depleted.
The hydro electric performance depends essentially on
the usable altitude difference between upper reservoir
and lower reservoir, and hence the flow. In order to use
the “fuel” water in an optimal way, this flow has to be
monitored without any interruptions.

Ductus TT ECM IE
For pipes with a diameter of more than half a meter, acoustic flow measurement systems have long
established themselves as a reliable and convenient measurement method. Measurements in several
planes are a recommended method to determine the efficiency of the turbine without the need for
calibration meeting the latest international standards. Fixed installed equipment form the basis for
verifying the efficiency. A deterioration of efficiency can be detected right away and therefore
corrections can be initiated at an early stage.

A further area of application is the detection of burst pipes. Here, at least two systems have to be
permanently installed in the pipelines to be monitored. Because of the accuracy of our products
even small leakages can be detected instantaneously.

Advantages of Clamp-On Systems
A flow meter using clamp-on
transducers makes measuring
flow non-intrusive and easy from
the outside of the pipe.
The transducers are installed with
little technical effort and without
process interruption on the
pipeline.
Rotationally symmetric flow profiles
can be determined with a single

Water Supply
Although there is enough water on earth and it is not
consumed but merely used, drinking water starts to
get short. The uneven distribution of water amongst
the regions, the rising population and our carelessness
leads to a shortage of fresh drinking water.
In the future more and more pipelines for drinking
water will be built all over the globe. In order to
operate huge and complex pipe networks efficiently,
flow measurement will be necessary.

ReVision®
Concept Innovation
Space constraints and/or appropriate
application configurations lead to
complex industrial pipe flows which
contain elbows, tees and/or other
disturbing and non-uniform elements.
This leads to difficulties in install-
ing flow meters at a recommended
“optimum” location, which is defined
by a minimum distance upstream or
downstream of known disturbances
like an elbow or pump where a fully
developed velocity profile is present.
Even with multiple flow sensors, there
may still be a significant error which is
known as the profile factor.
flow meter after a 90° elbow
flow meter after two out of plane changes in flow direction
Prior knowledge of the profile factor can be used to correct the velocity measurements made by flow sensors
to a true spatially averaged velocity. The ReVision®
acoustic system provides detailed information on the
flow velocity profile and an accurate measurement of the flow rate can be achieved by rebuilding the whole
flow velocity profile across the pipe using predetermined conduit configuration parameters and correction
factors.
Asymetric and Swirls
Compensation
Swirl is normally generated by two or more out of plane changes in flow direction (e.g. one elbow/tee that
goes from vertical to horizontal followed by an elbow/tee that changes the direction of flow in the horizon-
tal plane). Swirl is present to some extent in almost every application and can generate significant trans-
verse velocity components plus it takes a long distance to dissipate. If the swirl is not centred, it can cause
significant errors. Thanks to the predetermined conduit configuration parameters and correction factors,
the flow meter measurement accuracy is kept when asymmetric profiles and swirls are present in the pipe.
Flow meters are also sensitive to velocity profiles where there is a large rotational component (swirl).

Waste Water
Drinking water is not the only area requiring flow
measurement. The disposal and cleaning of waste
water is of equal importance.
Waste water contains a multitude of organic sub-
stances which used to be dumped directly into the
soil or the nearest river. As awareness has increased,
most discharges are now treated to assure long term
sustainability. The contamination of surface waters
has now been reduced and the oxygen content could
be increased once again. Due to the advance of waste
water treatment around the world nature was able to
regenerate in many places. Today’s civilization is un-
thinkable without functioning water treatment plants.
Modern plants are highly complex systems.
They consist of channels for waste water flow, facilities for
waste water collection and clarification plants. HydroVision
can complete flow measurements in all of these areas.

For sewage-treatment plants flow measurements are primarily installed for internal reasons,
for example to control specific plant components with flow dependency or for controlling
additives. International regulations, for example the EU-Directive for handling municipal waste
water, require a continuous surveillance of waste water flow. Defective flow measurements
on sewage-treatment plants can therefore influence their operation, but there can also be legal
or environmental consequences.

Q-Eye Radar MT is an extremely versatile flow mea-
surement system designed for continuous operation
and suitable for measurements of flows not only in
rivers and open channels, but also in municipal waste-
water and storm water sewers. Compact construction
combined with the contact-free measurement princi-
ple enables an easy installation and use. The maximum
permissible installation height above the surface is 30
m. For waste water applications we suggest 10 m.
The ultrasonic depth sensor operates by energizing a
piezoelectric transducer with an electronic pulse. This
pulse creates a pressue wave that travels to the flow
surface where a portion returns to the transducer. Our
transmitter offers the best in liquid measurement. It is
easy to install, eliminates maintenance caused by sen-
sor fouling and your personnel do not get in contact
with the fluid during installation.

AquaProfiler®
AquaProfiler®
The AquaProfiler®
is a line of acoustic flow meters for
permanently installed and portable applications. The
AquaProfiler®
precisely measures water velocities in
open channels and pipes.
With its high accuracy and competitive cost, the Aqua-
Profiler®
is a perfect choice for long-term real-time
monitoring or to obtain instantaneous measurements
where time savings are an important aspect. It uses ad-
vanced Doppler technology to establish the velocity in
many separate space points (cells) along the measure-
ment axis and develop the flow profile.
22

Permanently installed applications
The AquaProfiler®
MT and MC are profiling instruments designed for in-situ installations.
With the 2-dimensional velocity sensor and a resolution of max. 64 cells, the systems are the best choice
for flows affected by variable backwater, sluggish, slow moving flows, ice-affected flows, tidal flows and
flows where flow reversals may occur. Combined with an integral pressure sensor for determining the
depth, the meter is using a numerical model for averaged velocity in the entire cross section and the
continuity equation to calculate flow. Alternatively, the index-velocity method can be used, as the sensor
gives an index velocity for a significant part of the flow which can easily be related to the mean velocity
of the cross section.

The AquaProfiler®
M-Pro is an instrument that oper-
ates in a manner very similar to an Acoustic Doppler
Current Profiler (ADCP). The primary difference is
that the probe is kept fixed on the channel bottom
and provides vertical velocity data in up to 128 cells.
Due to the very small cell size (0,005 m), a resolution
of the vertical velocity distribution can be achieved
which was unthinkable a few years ago.
The AquaProfiler®
M-Pro is a device that extends
the capability of flow measurements to a range
of situations under which standard current meter
techniques (mechanical or electromagnetic) cannot
be used.
The AquaProfiler®
M is a high-precision point-
velocity meter. It uses a complex pulse-to-pulse co-
herent sampling scheme that gives the instrument
high precision in measurement of velocity within a
very small volume a few centimeters in front of the
sensor. The small sampling volume provides velocity
data that can be considered as point velocities.
The advantages over mechanical meters include:
no moving parts, thus less maintenance required,
minimal flow disturbance, velocity measurements
as low as 0,005 m/s and minimum operating depth
of 2 cm.
